Took a look, seems similar to the one we put in this weekend, the one we have worked and matched up to the nut we took off the original engine mount. It just seems like the bolt is just a tiny bit shorter than ideal but does work.

Getting my car slowly put back together with the help from Chuck, on the interesting side of things, I do now have a spare 88mm pulley as the one I took off my old seized SC is smaller (thinking it is the mythical 84mm pulley Sam never sold anyone). Planning out numbers so we do not over spin the SC but also make optimal power, chuck & I were playing ideas on what we could do to.

Good to hear you got it together.

I have the 85mm that jinxx has,not installed tho,iam thinking the 88mm would be real nice power,approx 10lbs of boost,i just don't want to kill the sc unit by over spinning it with the 85mm,hopefully jinxx will keep us posted on how his is performing over next few months,i plan to upgrade to cjm fuel system over this upcoming winter and a few other mods to.

Jinxx should be good if he shifts at 7k RPM, and also remember how often & how long you are at the top of the powerband. When we do my tune, the shift light will be reduced to 6800-7000 and probably dial back the top end for safety possibly but who knows...may as well just go for it!!

Ya might aswell go big lol, I drive my car at the top of the rev range most of the time, with the 92mm pulley it's great power,still get decent traction as long as iam smooth with clutch.

What tuning are you going with?

Jinxx 07-20-2016 05:42 AM

I actually Dynoed mine to 7.5k ... And from the graphs wasn't much more after 7k ... And for real world driving I would be shifting between 6.8k-7k that would be right at 90k on the supercharger .... Still drives well with no issues ( knock on wood )lol

I have my shift light set for 6.8k just to be safer

That sounds about right, I think even with the 1.5/2 kit (straighter pipes & more open), there are still some top end limitations somewhere. Either in the intercooler (SC is much much smaller than the TT guys) or on the back pressure side and keeping the overlap in check.

Hey jinxx how is the car running with the 85mm pulley?any updates?

Also did your blow off valve start to make a flutter sound before you had trouble with it the first time? Mine is still working fine just noticed that the sound has changed abit while shifting thru the gears,before it just sounded like it was releasing alot of air pressure off the gas but now it flutters abit,its still closing so it seems fine but maybe it needs to be tightend? These blow off valves are pretty new to me.

Everything is running fine no issues .. So far lol... And the valve could be sticking a little.. Mine stuck more when I had it set very loose .. I tighten it up a few turns and get very little flutter .. When mine stuck it was just stuck no air release then ... You can try loosing it a turn or two

Good to hear it's running good,id imagine it's pretty quick with that pulley now.

I lubricated the valve before installing,it seems to be working fine just all of a sudden the sound changed, I might pull the bumper and take a closer look

Hey tiller how is your car doing ...have you changed to the 85mm pulley yet ...and issues with it so far ?

Cars running great jinxx, still running the 92mm, seb changed timing slightly,ecutek works great, iam currently changing from 91 octane to 110 unleaded,ill do the cj fuel return and new pump hat over this upcoming winter then change to 85mm pulley for next summer, seb says running on 110 will make a huge difference for tuning and multiple other factors,prettty well gona have my own gas station in my garage for 110 lol

Jinxx 09-11-2016 04:07 PM

Yea I can imagine .. 110 with 85mm should put down 540 ish ... I daily drone mine so I needed 93octane tune ... You will like the 85mm tho boost much sooner

Ya my z isn't my daily driver so iam gona get 110 race fuel in 54 gallon drums, I've been using klotz octane accelerator lately and it helps alot and brings up octane alot that helps with knock and detonation.

Where you get that .. Never heard of it
